| Outline of Final Research Achievements |
In this study, new porous anion conducting polymer was developed as an ionomer of membrane electrode assembly in solid alkaline fuel cell to efficiently transfer anion and fuel gas to the electrochemical reaction site. It is clarified that the developed polymer has high chemical durability owing to its all-aromatic backbone and also has high anion conductivity despite of lower water uptake by using porous structure in molecular level for ion transporting passway.

| Academic Significance and Societal Importance of the Research Achievements |
固体アルカリ燃料電池では、化学耐久性に優れ、化学反応サイトにイオン、燃料ガスを効率良く移動させるアニオン伝導材料の開発が重要である。本研究では、高分子骨格中に分解の起点を持たない全芳香族高分子を用いることで高い化学耐久性が得られる事、多孔性高分子の分子細孔を用いることで、効率良くイオンや燃料ガスを透過させる事が可能であるという事を明らかにし、固体アルカリ燃料電池に使用するイオノマーの、重要な材料開発指針を提供できた。
